Abstract

Un récipient comporte un panneau de base, au moins un panneau latéral remontant du panneau de base et au moins un panneau d'extrémité remontant du panneau de base. Au moins un coin est formé par la jonction entre le panneau latéral et le panneau d'extrémité. Un rebord sallonge de façon latérale vers l'extérieur en prenant naissance sur les rebords supérieurs du panneau latéral, du panneau dextrémité ou du coin. Une structure moulée par injection occupe la longueur d'au moins une partie du rebord. Cette structure moulée par injection comporte une partie de base adjacente aux rebords supérieurs de la paroi latérale et de la paroi d'extrémité. Une partie distale sallonge de façon latérale vers l'extérieur sur la partie de base. Enfin, une échancrure pratiquée dans la partie distale occupe la longueur dau moins une partie du rebord du récipient. Linvention concerne également un appareil permettant de former le récipient et un procédé de fabrication connexe.
